Dive Warnings

• The diving features of this device are for use by certified

divers only. This device should not be used as a sole dive

computer. Failure to input the appropriate dive-related

information into the device can lead to serious personal injury

or death.

• Make sure that you fully understand the use, displays, and

limitations of your device. If you have questions about this

manual or the device, always resolve any discrepancies or

confusion before diving with the device. Always remember

that you are responsible for your own safety.

• There is always a risk of decompression sickness (DCS) for

any dive profile even if you follow the dive plan provided by

the dive tables or a diving device. No procedure, diving

device, or dive table will eliminate the possibility of DCS or

oxygen toxicity. An individual's physiological make up can

vary from day to day. This device cannot account for these

variations. You are strongly advised to remain well within the

limits provided by this device to minimize the risk of DCS.

You should consult a physician regarding your fitness before

diving.

• Do not dive with a gas if you have not personally verified its

contents and input the analyzed value to the device. Failure

to verify tank contents and input the appropriate gas values

to the device will result in incorrect dive planning information

and could result in serious injury or death.

• Diving with more than one gas mixture presents a much

greater risk than diving with a single gas mixture. Mistakes

related to the use of multiple gas mixtures may lead to

serious injury or death.

• Always ensure a safe ascent. A rapid ascent increases the

risk of DCS.

• Disabling the deco lockout feature on the device can result in

an increased risk of DCS, which can result in personal injury

or death. Disable this feature at your own risk.

• Violating a required decompression stop may result in

serious injury or death. Never ascend above the displayed

decompression stop depth.

• Always perform a safety stop between 3 and 5 meters for 3

minutes, even if no decompression stop is required.

Dive Modes

The Descent Mk1 device supports five dive modes. Each dive

mode has four phases: dive pre-check, surface display, in-dive,

and post-dive.

Single-Gas: Allows you to dive with a single gas blend.

™

Diving

WARNING

Multi-Gas: Allows you to configure multiple gas blends and

switch gases during your dive. This mode supports one

bottom gas, and up to five additional gases for

decompression or backup.

NOTE: Backup gases are not used in no-decompression limit

(NDL) and time to surface (TTS) decompression calculations

until you activate them during a dive.

Gauge: Allows you to dive with basic bottom timer features.

NOTE: After diving in gauge mode, the device can only be

used in gauge or apnea mode for 24 hours.

Apnea: Allows you to free dive with apnea-specific dive data.

This mode has a higher data refresh rate.

Apnea Hunt: Similar to the Apnea dive mode, but tuned

specifically for spearfishers. Start and stop tones are

disabled.

Dive Setup

You can customize the dive settings based on your needs. Not

all settings are applicable for all dive modes. You can also edit

the settings before you start a dive.

Hold UP, and select Dive Setup.

Gases: Sets the gas blends.

Conservatism: Sets the level of conservatism for

decompression calculations. Higher conservatism provides a

shorter bottom time and a longer ascent time. The Custom

option allows you to set a custom gradient factor.

Water Type: Allows you to select the water type.

PO2: Sets the maximum partial pressure of oxygen in bars.

Alerts: Allows you to set alerts for depth and time. You can

enable different alerts for different dive modes.

Apnea Surf. Alert: Allows you to set alerts for apnea surface

intervals.

Safety Stop: Allows you to set the safety stop duration.

End Dive Delay: Allows you to set the length of time before the

device ends and saves a dive after surfacing.

Backlight: Allows you to adjust the backlight settings for dive

activities.

Heart Rate: Allows you to enable the wrist heart rate monitor or

a chest heart rate monitor for dives.

NOTE: You can only view wrist heart rate monitor data during

a dive. You can view chest heart rate monitor data on your

Garmin Connect account after you complete the dive.

Double Tap to Scroll: Allows you to double tap the device to

scroll through the dive data screens.

Deco Lockout: Disables the decompression lockout feature,

which prevents too many decompression dives in a short

time period.

Starting a Dive

From the watch face, select

Select a dive mode

If necessary, select DOWN to edit the dive settings, such as

the gases, water type, and alerts

Select

Descend to start your dive.

The activity timer starts automatically when you reach a

depth of 1.2 m (4 ft.).

NOTE: If you start a dive without selecting a dive mode, the

device uses the most recently used dive mode.

Select DOWN to scroll through the data screens and dive

compass.

TIP: You can also double tap the device to scroll through the

screens.
